LG's augmented reality app Metro Scanner is pretty cool
Say what you want about LG but their custom Windows Phone software is hands down the best of all the OEMs today. Between offering $30 worth of apps for free (including the amazing Weave) and their homemade stuff like Voice to Text, ScanSearch and Metro Scanner (and a bunch of other tools, like panoramic camera), they really offer quite the one-two punch to HTC and Samsung.
ScanSearch and Metro Scanner are great because they are so-called augmented reality apps. Basically they take advantage of the phone's accelerometer, compass and camera to show you things you can't see, like bars, restaurants, or in the case of Metro Scanner, subway stations in your local city.
Metro Scanner works "world wide" and while we couldn't vouch for that it did a swell job in New York City. You launch the app, it grabs a GPS fix (can take a few seconds, though it has a progress bar, natch) and then it shows you where the nearest subway is in relation to you. Holding the phone flat gives you a map with compass, holding it up uses the camera to show you where it is as if you could see through all the buildings. Tapping the station gives you directions.
Metro Scanner was just updated to v1.2 to fix a compass bug and all we have to say about the app is that it's pretty darn cool, LG. Our next hope? Microsoft releases those camera and compass APIs so 3rd party developers like Layar can join in on the fun.
